When "memory" node is being processed in fdt_pack_reg() on ARM64
platforms, an unaligned bus access might happen, which leads to
"synchronous abort" CPU exception. Consider next dts example:
/ {
#address-cells = <2>;
#size-cells = <1>;
memory@80000000 {
device_type = "memory";
reg = <0x0 0x80000000 0x3ab00000>,
<0x0 0xc0000000 0x40000000>,
<0x8 0x80000000 0x80000000>;
};
};
After fdt_pack_reg() reads the first addr/size entry from such memory
node, the "p" pointer becomes 12 bytes shifted from its original value
(8 bytes for two address cells + 4 bytes for one size cell). So now it's
not 64-bit aligned, and an attempt to do 64-bit bus access to that
address will cause an abort like this:
"Synchronous Abort" handler, esr 0x96000021, far 0xba235efc
This issue was originally reported by David Virag [1] who observed it
happening on Samsung Exynos7885 SoC (ARM64), and later the same issue
was observed on Samsung Exynos850 (ARM64).
Fix the issue by using put_unaligned_be64() helper, which takes care of
possible unaligned 64-bit accesses. That solution was proposed by Simon
Glass in the original thread [1].

Change type of ulong env_get_bootm_low() to phys_addr_t env_get_bootm_low().
The PPC/LS systems already treat env_get_bootm_low() result as phys_addr_t,
while the function itself still returns ulong. This is potentially dangerous
on 64bit systems, where ulong might not be large enough to hold the content
of "bootm_low" environment variable. Fix it by using phys_addr_t, similar to
what env_get_bootm_size() does, which returns phys_size_t .

This series is the culmanation of the current line of refactoring
series. It adjusts pxe to call the booting functionality directly
rather than going through the command-line interface.
With this is is possible to boot using the extlinux bootmeth without

It also updates fastboot to do a similar thing.

- Fix #if logic in android_ab command
- Fix ANDROID_AB_BACKUP_OFFSET in android_ab
|

Currently, setting CONFIG_AB_BACKUP_OFFSET in a target's defconfig will
not actually enable the #if protected code in android_ab.c. This is
because "CONFIG_" should have been prepended to the config macro, or the
macros defined in kconfig.h could have been used.
The code included by ANDROID_AB_BACKUP_OFFSET has been refactored to no
longer be conditionally compiled by preprocessor conditionals and
instead use C conditionals. This better aligns with the Linux kernel
style guide.

According to README CFG_SYS_BOOTMAPSZ section, in case both "bootm_low" and
"bootm_size" variables are defined, "bootm_mapsize" variable is not defined
and CFG_SYS_BOOTMAPSZ macro is not defined, all data for the Linux kernel
must be between "bootm_low" and "bootm_low" + "bootm_size".
Currently, for systems with DRAM between 0x4000_0000..0x7fff_ffff and with
e.g. bootm_low=0x60000000 and bootm_size=0x10000000, the code will attempt
to reserve memory from 0x4000_0000..0x4fff_ffff, which is incorrect. This
is because "bootm_low" is not taken into consideration correctly.
The last parameter of lmb_alloc_base() is the maximum physical address of
the to be reserved LMB area. Currently this is the start of DRAM bank that
is considered for LMB area reservation + min(DRAM bank size, bootm_size).
In case bootm_low is set to non-zero, this maximum physical address has to
be shifted upward, to min(DRAM bank start + size, bootm_low + bootm_size),
otherwise the reserved memory may be below bootm_low address.
In case of multiple DRAM banks, the current change reserves top part of
the first bank, and reserves the rest of memory in the follow up banks.

Currently, if boot with extlinux.conf and do not set the fdt
U-Boot will provide its own device tree. This behavior is
beneficial if the U-Boot device tree is in sync with Linux,
but it totally halts the booting of pre-dtb kernels (3.4 for
example) since it uses ATAGs. To fix this, pass `-` in the
fdt extlinux field as a signal that no tree should be used.

With the relatively new button API in U-Boot, it's now much easier to
model the common usecase of mapping arbitrary actions to different
buttons during boot - for example entering fastboot mode, setting some
additional kernel cmdline arguments, or booting with a custom recovery
ramdisk, to name a few.
Historically, this functionality has been implemented in board code,
making it fixed for a given U-Boot binary and requiring the code be
duplicated and modified for every board.
Implement a generic abstraction to run an arbitrary command during boot
when a specific button is pressed. The button -> command mapping is
configured via environment variables with the following format:
button_cmd_N_name=<button label>
button_cmd_N=<command to run>
Where N is the mapping number starting from 0. For example:
button_cmd_0_name=vol_down
button_cmd_0=fastboot usb 0
This will cause the device to enter fastboot mode if volume down is held
during boot.
After we enter the cli loop the button commands are no longer valid,
this allows the buttons to additionally be used for navigating a boot
menu.

Sometimes the kernel is built as an EFI application rather than a
binary. We still want to support compression for this case.
For arm64 the entry point is set later in the bootm_load_os() function,
since these images are typically relocated due to the 2MB-alignment
requirement of arm64 images. But since the EFI image is not in the same
format, we need to update the entry point earlier.
Set the entry point always, for kernel_noload to resolve this problem.
It should be harmless to do this always.
